Abstract

In this paper, we consider the singular stress of G-10CR glass-epoxy laminates with a broken layer under tension at low temperatures. The composite material in generalized plane strain is assumed. Fourier transforms are used to formulate the problem in terms of a singular integral equation. The order of stress singularity around the tip of a crack which is normal to and ends at the interface between orthotropic elastic materials is obtained. The singular integral equation is solved by means of the Gauss-Jacobi integration formula. Numerical results for the stress intensity factor and the order of stress singularity at different temperatures are obtained and are presented in graphical form.
